"At the beginning of next year we've got Broken Bells and Bruce Springsteen," he told Hits Daily Double.

"Then we've got Lea Michele from Glee coming, and we've got Foster the People up next. Then we've got Pharrell and Solange, and obviously, at some point Beyoncé will put a record out, and when she does it will be monumental. So we're in really, really good shape."

Discussing the success of One Direction's album Midnight Memories, which was released in the US via Columbia, he described Simon Cowell as "one of the best A&R people I've ever worked with.

"In his field he is the best, the same way as when Russell Simmons and Rick Rubin did Def Jam. I feel really good about One Direction, and in the next few months I have one or two others up my sleeve who will, hopefully, be similar in stature. And I'll still be here to talk to you in a year's time."
